1. A pixel circuit, comprising:
a driving circuit coupled to a grayscale data signal terminal, a scan signal terminal, a first power supply voltage terminal, an enable signal control terminal and a light-emitting device; the driving circuit being configured to control on and off of a current path for transmitting a driving current signal under control of a scan signal received at the scan signal terminal and a signal received at the enable signal control terminal;
a control circuit coupled to a control signal terminal, a first node, a first enable signal terminal and a second enable signal terminal; the control circuit being configured to transmit a first enable signal received at the first enable signal terminal or a second enable signal received at the second enable signal terminal to the first node under control of a control signal received at the control signal terminal; and
a gating circuit coupled to the enable signal control terminal, the first node, a first constant voltage signal terminal and a second constant voltage signal terminal; the gating circuit being configured to, in response to an enable signal received at the first node, transmit a first constant voltage signal received at the first constant voltage signal terminal or a second constant voltage signal received at the second constant voltage signal terminal to the enable signal control terminal.
